Feit 18650 adapter for the 250 lm & the 500 lm flashlights

thingiverse

This is a reworked version of kuma_san's outstanding 18650 adapter designed specifically for the 3AAA battery flashlight. I made significant modifications to make it compatible with my Feit 250 lumen flashlight, while also incorporating minor tweaks to simplify printing. Additionally, I included an adapter for the 18650 battery to fit the 3 C cell version of the Feit 500 lumen flashlight. Both models were once sold by Costco a couple of years ago. The smaller adapter is printed without support but with a brim, while the larger 3 C cell adapter can be printed without support and does not require a brim. Attach wire according to the pictures provided. Please note that the same disclaimer applies as in the original version: 18650 lithium-ion batteries can be hazardous. I am not responsible for any accidents, damage, or fires resulting from misuse of these batteries.
